does anyone know??

i hane a d.a. .45 cal smith & wesson i had to write a letter to S&W i gave them all the markings they sent me a letter a couple weeks later they gave me the date of the gun and also a little bit of history on the gun but they said if i wanted them to search there archives i would have to send them $30 i never did because they gave me the little bit of information i needed this was about seven years ago but im sure theyll still help keep us informed.

I looked in my 2007 Standard Catalog of Firarms 17th Edition and this is what is said about the S&W Model 65 .357. The catalog says "This is the stainless steel version of the Model 13 M&P .357 Magnum. It was introduced in 1974." That is all it had to say about it except it gave the values for New In Box $350, Excellent $300, Very Good $275, Good $225, Fair $175, Poor $125. That is all there was in the Catalog. Hope this helps answer at least a few of your questions.

By the way just some information on the S&W Model 13 that your firearm is modeled after and here is the information on the Model 13. "This is simply the Model 10 M&P chambered for the .357 Magnum and fitted with a heavy barrel. It was introduced in 1974."
